Sean your comments are enlightening.

What is the best solution here?
One approach might be to maintain two separate greenlist files - one that
is plain non-regexp strings, and (a presumably much smaller) one with
regexps. Don't hand grep anything more than you want it to be parsing.
yeah soon after I sent this email I also thought of the mentioned
solution.
So the add_to_wl script will check for an exclude list of the
mass domains and if _not_ found will add to the domain_wl as
follows:
(_dot_)*(_at_)domain(_dot_)com
otherwise if this type of domain is found viz.
aol.com, hotmail.com, then the literal non-regex email address
will be added to a email_wl.
For the former I process with egrep and the later, the look(1) utility
seems to be most suitable.
(pity about the scalability of egrep -f ; my first encounter)
